I want to receive emails on my server inside an enterprise network.
Emails are handled by an Exchange Server - my server uses a company-internal SMTP Relay to push Emails to the users. But how can I receive Emails?

On possibility would be: I have an Exchange user - can I use his mailbox?

The other one, i would prefer: The mentioned server has an entry in the DNS so the name is resolved properly - I could have an Email-server on it that accepts Emails.
But what tools are nice to use and how can i achieve that the server is accepting emails?

Servers: Debian Sarge (Testmachine), RedHat Enterprise Linux 3; To send Emails i am using postfix

Thanks for your help in advance,

I don´t really understand ur prob....hmm...u want to access ur exchange account from a linux server?

To put it in one sentence:

I want an internal running linux server to act as a email server i can send emails to

then configure it as a smarthost for ur qualify_domain.

Where do i do that and what is a smarthost at all?

so what are you planning to do?
internal linmailserver for:
-receiving external mails?
-receiving only internal mails?
-> from other servers or only from users?
-separate user-accounts on this linbox?
-> if yes, then create another account in email-client and it´s done!
-only maintenance account = forwarding from exchange to LIN?
??

I just want to receive internal email, no external.

All Email should be fetched by postmaster - perhaps i will split it to users on the linux box later on (this is mainly for communication with applications on the server)

b.t.w. what kind of server do i have to set up to receive the mails directly? (Sending them to blabla@mybox.mycompany.net ?)

Thanks for your help,

should work if you set up your postfix server (postfix.domain.intra) and
configure postfix.domain.intra as a smarthost in exchange.
then you can send email via ur exchange account to postfix.

Here comes the problem: I have no access to Exchange

ur sending mailserver mustn´t do DNS for sending email to postfix.domain.intra.
that´s why u must configure postfix.domain.intra as a smarthost.

what´s about that?!:
configure postfix (IP=192.168.1.10) allowing ip_literals and send emails from ur client to blabla@192.168.1.10

When mailing to the box via ip-adress i always get "No valid recipients" (on the site i am sending)

thats the point. ur box must be configured to allow ip´s in email-addy!
keyword ip-literals!
at the moment I don´t know where this is set in postfix config

On the sender (in this case the exchange server i cant access) or the recipient server (my box)?

think ur box is enough, but don´t know if the exchange will block/deny outgoing "ip-mails"!
try it.

ok leisure-time :-))
cu tomorrow
